I think I’m the last person in the world to realize that Cinnabon was intended to rhyme with cinnamon. Most cinnamon-flavored baked goods are bun-shaped (which is close enough to ‘bon’ that that’s what they must’ve been going for, and what I always just assumed; or perhaps ‘bon’ as in the French word for good) [don’t expect me to actually look this up].
Where I come from we mostly call those pastries, cinnamon rolls. There’s less rhyme with Cinnaroll, however; and less recall, too, I suspect.
Maybe newborn babies don’t know that either. But give them time.
